I'm starting to make a list of baby gear I'll need for LO2. I didn't BF with LO1 so this is new territory for me. I'm a WAHM, and ideally I'd like to EBF. I've seen so many "must-haves for breastfeeding" lists that's include pumps/bottles and I'm wondering if it's necessary that I invest in one before the birth? Is it something that's best to have on hand right away, or could I just wait and see if pumping is a road I have to go down before purchasing?
